Research

My research focuses on the impact complex demographic histories have on evolutionary processes through time and space. The interactions of mutation, gene flow, genetic drift, and selection can be greatly altered in non-equilibrium scenarios. Most recently I have addressed these questions by studying local adaptation during range expansions. I have previously investigated the accuracy of methods for estimating effective population size in the presence of migration. During my current post-doc at the University of Toronto, I am conducting another methods-testing study to investigate the bias introduced by various mating systems in estimating the distribution of fitness effects for new mutations.

I generally aim to address my research questions through both theoretical simulation-based approaches, as well as through validation and testing with empirical data. My future work will involve comparing several range expansion models to real-world genomic data from humans and other species.

I maintain an active interest in the role of data accessibility and archiving in scientific research and in scientific reproducibility, which I have worked on with the UBC reproducibility group.

My undergraduate research involved examining the effects of biological invasions on genetic diversity and population structure, and using this information combined with approximate Bayesian computation to describe the history of invasion of the plant Silene latifolia.
